3M 7000045892 Metal Finishing Wheel 12x2x5 in 5A Medium

Product Description

The 3M 7000045892 is a convolutely wound metal finishing wheel designed to produce uniform satin finishes on metal surfaces. Built around a solid core, it uses a medium-grade aluminum oxide abrasive mineral at a 5A medium density rating. The convolute construction distributes abrasive material evenly throughout the wheel, delivering consistent cut and finish across the contact face. At 12 inches in diameter, 2 inches wide, and with a 5-inch arbor hole, it mounts to bench grinders, pedestal grinders, or finishing machines used in fabrication and metalworking shops. Installation and operation are handled by machinists, metal fabricators, and trade professionals working with ferrous and non-ferrous metals.

This wheel is suited for satin and butler finishing applications on flat or contoured metal workpieces. It performs well in production environments where a repeatable, uniform surface finish is required before plating, coating, or final inspection. The medium 5A density makes it appropriate for general-purpose finishing work where aggressive stock removal is not the goal. It is sold as a single wheel and is intended for use on powered finishing equipment at the arbor size specified.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive wheel mounting procedures. Always power down and lock out the finishing machine before mounting or removing the wheel. Inspect the wheel for cracks or damage before installation and verify that the machine's rated speed is compatible with the wheel's maximum operating speed. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
